We used the manipulateplanet tool developed by [1]} to get an estimate on the planetary composition. The derived value of mass and a minimum core pressure (3020 GPa) supports a planet with an iron core (Fe : 58.7% by mass), Silicate mantle (MgSiO\(_3\)  : 40.9%) and a thin layer of water on the surface (H\(_2\) O : 0.9%), favouring the rocky composition discussed in the literature.
